Introduction

Standard Background and Scope of Application

GH/T 1435-2023 was released by the All-China Federation of Supply and Marketing Cooperatives in September 2023. It is my country's first industry standard specifically for the cold storage and heat preservation circulation of horticultural products. This standard fills the gap in the standard for the combination of traditional cold chain and new cold storage technology, and is applicable to e-commerce express delivery and trunk transportation scenarios of products such as fruits, vegetables, and flowers.

Core terminology definitions

Terms	Definition	Classification
Cold storage and insulation box	An insulation box that maintains the temperature inside the box through a cold storage agent	By purpose: express delivery/vehicle-mounted By cooling method: cold exchange type/cold charging type
Cold storage agent	Food-grade mixed medium that can store cold	Form: cold storage plate/bag/bottle

Key technical requirements

1. Equipment selection specifications

Car-mounted box: must comply with GB/T 1413 container standard, load-bearing ≥ 1.5 tons
Express box: dimensions comply with GB/T 16471, marked with storage and transportation marks specified in GB/T 191
Material safety: food-grade PP or PU material, total colony count ≤ 100 CFU/cm²

2. Temperature control points

Typical case: Strawberry transportation needs to be maintained at 0-3℃, the phase change temperature of the refrigerant should be set to -3 to -5℃, and the weight ratio of the refrigerant to the cargo is recommended to be 1:5

Operation process analysis

Stage	Technical requirements	Parameter indicators
Precooling	Synchronous precooling of box and goods	Temperature difference ≤2℃
Cold storage	Freeze the cold storage agent in the quick-freezing warehouse	Plate: 7-10℃ below the phase change point Bag: 5-7℃ below the phase change point
Transportation	Temperature monitoring frequency	Vehicle-mounted: ≥1 sensor per 10m³

Implementation suggestions

1. Equipment selection strategy

Priority for e-commerce scenarios class=instrument>Cold exchange insulated box, and cold charging vehicle box are recommended for trunk transportation. Humidity sensors are required for the transportation of roses and other flowers.

2. Cost optimization plan

Refrigerant with latent heat of phase change＞200kJ/kg can reduce the amount by 20%
Use the formula in Appendix A to accurately calculate the demand for refrigerant and avoid excessive configuration

3. Risk control

For tropical fruits such as mangoes, attention should be paid to the chilling temperature critical point (≥10℃), and a phased cooling strategy is recommended.
